SIGHT FOR FIREARMS.

Specification of Letters Patent.

Patented Sept. 27, 1910.

Application led January 10, 1910. Serial No. 537,108.

To all whom it may concern:

Be it known that I, HENRY L. LovnJoY, a subject of King Edward VII, residing at Melrose, in the county of Middlesex and State of- Massachusetts, have invented new and useful Improvements in Sights for Firearms, of which the following is a specification.

This invention relates to improvements in sights for lire arms, and one object is to provide a gun sight having a plurality of leaves which may be conveniently moved into and out of the line of vision, and the object is further to provide means to securely hold the leaves in either raised or lowered position. i

Another object is to provide means for protecting the sight leaves from injury when lowered and further to provide means to protect the leaves from dust, dirt, ice and other foreign matter which would clog the sight orifices and render them unfit for immediate use.

The object is still further to provide a cap for protecting the leaves from foreign matter with an external sight which may be used when the cap is in place covering the other sights.

The invention consists in the novel features of construction and in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims.

Referring to the drawings: Figure 1 is a plan of a gun sight embodying my invention with its cap removed. Fig. 2 is a side elevation of the gun sight with the cap in place. Fig. 3 is a sectional view taken on line 3#3 of Fig. 2, looking toward the right. Fig. 4 is a longitudinal vertical section of the sight with the cap in place. Fig. 5 is a vertical longitudinal section of the sight with the cap removed and the notched leaf raised, the spring tongue being partly broken away to save space. Fig. 6 is a vertical longitudinal section of the sight with the peep sight leaf raised in position for use. Fig. 7 is a vertical longitudinal section of the sight with the peep sight leaf and the pin-hole sight leaf raised in the positions they occupy when the pinhole hight leaf is being used.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 10 is a base or support which may be secured to any suitable part of a gun in any usual or desired manner and which in this instance is provided with a spring tongue 11 provided with a slot 12 to receive an elevating device 13 of well known construction. The support 10 is provided with two lateral parallel protecting walls 14, 14 between which a notched or open sight leaf 15 is mounted on a transverse pivot 16, said leaf being provided with a usual notch 17.

Mounted between the walls 14 is a peep sight 18 on a transverse pivot 19 independent of the pivot 16 and having a distinct axis. Also mounted on the pivot 19 is a pin-hole sight leaf 20 having an ear 21 located between two ears 22, 22 on the leaf 18. The peep sight leaf 18 is provided with a suitable aperture 23 and the pin-hole sight leaf is provided with a suitable aperture `24, the median axial lines of these apertures being located at equal distances from the axis of the pivot 19 so that when each of the leaves 18 and 2O is raised the median axial lines of their respective apertures coincide with the line of vision A-A, which line is shown in Figs. 4, 5, 6 and 7. Likewise, when the notched sight 15 is raised in position for use, the line of vision A-A passes through the proper part of the notch 17.

The leaf 15 is provided with two flat faces 25 and 26 located at right angles to each other, either of these faces being adapted to engage a flat spring 27 secured at one end to the face or support 10, said spring coperating with the former face to hold said leaf in its lowered position, as shown in Fig. 4 and said spring coperating with the latter face to hold said leaf raised in position for use, as shown in Fig. 5. In like manner, the ear 21 of the leaf 2O is provided with two flat faces 28 and 29 located at right angles to each other and the leaf 18 is provided with corresponding flat faces, all of which cooperate in an obvious manner with the spring 27 to hold said leaves in either raised or lowered position, as may be desired, it being evident that each of the leaves will be firmly held in the desired position without danger of being displaced by a ar.

The protecting walls 14, 14 are of such height as to extend entirely above each of the three leaves when said leaves are lowered, as shown in Fig. 4, thus protecting the leaves from injury in striking trees and rocks. To protect the sight leaves from dust, dirt, ice and other foreign matter when said leaves are not in use, I provide a cap 3() having lateral walls to it down closely over th-e sides and ends of the walls 14, 14 so as to exclude all dust and moisture, said cap being provided with suitable means for detachably connecting the same to the base 10, such means in this instance consisting of springs 31 formed on or secured to said cap on opposite sides thereof in any suitable manner, said springs being provided, respectively, with projections 32 extending inwardly and engaging longitudinal grooves 33, formed in opposite sides, respectively, of said base. This cap may be readily detached by an upward pull which will cause the springs 31 to yield and the projections 32 to pass out of the grooves 33.

To insure the orifices 23 and 24 being always free from foreign matter, I provide the cap 30 with a downwardly projecting internal spur 34 which, as shown in Fig. 4, enters both of said apertures when the cap is in place and thus excludes foreign matter therefrom. rl`he cap 30 may be, and pref-erably is, provided with a notched sight 35 of such height that the line of vision A--A passes through the proper portion of the notch 36 therein, said notch occupying the same position vertically that the notch 17 occupies when the leaf 15 is being used. Thus for ordinary shooting at close range the cap may be retained in place and the notched sight 35 thereon may be used in the customary and well known manner and during such time the leaf sights covered by said .cap are fully protected from foreign matter so as to be in proper condition for immediate use when the cap is removed.

Having thus described my invention, what I claim and desire by Letters Patent to se- Cure is:

1. A device of the class described having, in combination, a support, a peep-sight leaf, a pin-hole sight leaf, and a notched sight leaf, two of said leaves being pivoted on a common axis and the third leaf being pivoted on a distinct individual axis.

2. A device of the class described having, in combination, a support; a peep-sight leaf and a pin-hole sight leaf pivoted on a common axis on said support; and a notched sight leaf pivoted on said support on a distinct individual axis.

3. A device of the class described having, in combination, a support; a peep-sight leaf and a pin-hole sight leaf pivoted on a common axis on said support; a notched sight leaf pivoted on said support on a distinct individual axis; and yielding means acting to hold said leaves in raised position for use.

4. A device of the class described having, in combination, a support; a peep-sight leaf and a pin-hole sight leaf pivoted on a common axis on said support; a notched sight leaf pivoted on said support on a distinct individual axis; and yielding means acting to hold said leaves in either raised or lowered position.
